Secure multi-party computation (MPC) allows several mutually untrusting parties to perform joint computations while keeping their inputs private. This project develops new techniques for constructing two-party secure computation protocols with low communication overhead. Building on the Principal Investigator's prior work for constructing special-purpose secure MPC protocols for greedy algorithms, this project develops new techniques that exploit the algorithmic structure of a function in order to develop more efficient secure computation protocols.

This research focuses on understanding the digital security and privacy needs of journalists and their sources to evaluate and design communication technologies that better support the fundamental operations of a globally free and unfettered press. Journalists -- along with their organizations and sources -- are known to be high-risk targets for cyberattack. This community can serve as a privacy and security bellwether, motivated to use new technologies, but requiring flexibility and ease-of-use. Many existing secure tools are too cumbersome for journalists to use on a regular basis.

Computer systems increasingly perform operations on critical and confidential data. Despite best efforts to protect this information, the side effects of computations using this data, e.g., the computation time, the power consumption, electromagnetic radiation, thermal emanations, and acoustics, can be used to decipher secret information even when it is encrypted.

More and more objects used in daily life have Internet connectivity, creating an "Internet of Things" (IoT). Computer security and privacy for an IoT ecosystem are fundamentally important because security breaches can cause real and significant harm to people, their homes, and their community.

Information about individuals is collected by a variety of organizations including government agencies, banks, hospitals, research institutions, and private companies. In many cases, sharing this data among organizations can bring benefits in social, scientific, business, and security domains, as the collected information is of similar nature, of about similar populations. However, much of this collected data is sensitive as it contains personal information, or information that could damage an organization's reputation or competitiveness.

Internet users may have compelling reasons to seek anonymity online, for example, to discuss stigmatizing issues with others like themselves, or to express dissident opinions. This project studies what people believe it means to be anonymous online, how their privacy and security are affected by their strategies to achieve anonymity, and how they are likely to use new anonymity services. These questions are important because the traceability of users? actions across sites and contexts is ever greater, increasing risks for users who may misjudge their actual anonymity.

While the mathematical study of cryptography has yielded a rich theory, and while the use of cryptography has become quite widespread, there is unfortunately still a significant gap between the theory and practice of cryptography. The goal of this project is to bridge this gap. The emphasis will be on the design and analysis of fundamental cryptographic primitives, such as hash functions and block ciphers, as well as other primitives derived from them, that are practical and yet theoretically sound. Indeed, hash functions and block ciphers are used in almost any cryptographic application.

The goal of this project is to provide protection against exploits through untrusted third-party software components and against malicious application manipulation. These problems constitute an important class of vulnerabilities in current software, and are tied to a common denominator -- the lack of ability to divide a program and the data manipulated by it in a fine-grained manner and to control the interactions between the resulting constituents.

A fundamental but challenging issue in information security is secure sharing and management of sensitive data and information among numerous organizations that form large-scale e-enterprises. Today, an increasing number of enterprises are using the Internet for managing and sharing users? and enterprise information through online databases. However, security and privacy of data is an overriding concern currently limiting the proliferation of information technology.

Security and privacy concerns in the increasingly interconnected world are receiving much attention from the research community, policymakers, and general public. However, much of the recent and on-going efforts concentrate on security of general-purpose computation and on privacy in communication and social interactions.
